Abstract

L'invention concerne un système d'armature permettant de régler un siège, en particulier un fauteuil (1) ou un canapé, comprenant un corps et/ou un pied pivotant (2), une partie d'assise (3), une partie dossier (4), un châssis (5) et un repose-jambes (6) dépliable. Le fauteuil (1) peut être basculé entre une position assise et une position allongée. La partie d'assise (3) peut être déplacée par l'intermédiaire de bras oscillants (7, 8) avant et arrière, articulés entre la partie d'assise (3) et le châssis (5), d'une position assise décalée vers le bord avant du fauteuil (1) à une position allongée décalée vers le bord arrière du fauteuil (1), le repose-jambes (6) étant couplé au mouvement de déplacement de la partie d'assise (3) de telle manière qu'il est basculé lors d'un coulissement de la partie d'assise (3). La partie d'assise (3) et le repose-jambes (6) comprennent de préférence un capitonnage continu (19) tandis que le repose-jambe (6) est basculé et sorti lorsqu'il est déplié de telle manière que le capitonnage (19) est tendu lorsque le repose-jambes (6) est déplié. Le repose-jambes (6) comporte un soutien de mollet (6a), équipé d'un repose-pieds (6b), pouvant être sorti par basculement et relié par le biais d'une chaîne à articulations (9), ayant en particulier la forme de leviers articulés en liaison active entre eux (13, 14, 15, 16), à la partie d'assise (3) et/ou au châssis (5), le repose-pieds (6b) et le soutien de mollet (6a) étant reliés ensemble dans l'articulation (20) de manière à pouvoir pivoter de telle manière que le repose-pieds (6b) peut être basculé de la position assise, dans laquelle le soutien de mollet (6a) forme un cache frontal et le repose-pieds (6b) est replié sous la partie d'assise (3), à la position allongée dans laquelle le soutien de mollet (6a) forme avec le repose-pieds (6b) une prolongation de la partie d'assise (3) contiguë à la partie d'assise (3), le repose-pieds (6b) étant basculé dans une position sensiblement horizontale prolongeant l'extrémité, opposée à la partie d'assise (3), du soutien de mollet (6a) déplié.
